Problems solved by technology
[0003] However, in Heilongjiang, Xinjiang, the main planting areas of China, and most areas in the south where the development of flax is relatively late, the problem of lodging resistance of flax is common, which greatly affects the development of the flax industry.
In the late growth period of flax, the branches gradually increase, the fruit grows gradually and becomes heavier, the center of gravity of the whole plant moves upward, and it is prone to lodging under the action of wind and rain. Once flax lodging occurs, it is basically difficult to stand up again. Harvesting will not be possible, flaxseed yield will be reduced and the germination rate will be low, flax fiber quality will be greatly reduced, income can be reduced by more than 50% or even disappear
[0004] The best way to solve the problem of lodging resistance is to breed lodging-resistant varieties. However, due to the characteristics of flax itself and the limitation of genetic resources, no fine varieties with strong lodging resistance characteristics and suitable for planting in various places have been selected so far.

Embodiment 1
[0061] The method for improving the lodging resistance of flax in this embodiment is as follows:
[0062] 1. Preferable varieties with certain lodging resistance, such as Zhonglin No. 1, Zhonglin No. 2, Zhonglin No. 3, Zhonglin No. 4, etc.
[0063] 2. Spring sowing flax. After the last crop is harvested, choose plowing when the soil is dry after winter, and raking the ground 15-20 days later to reduce the occurrence of soil diseases and insect pests of spring sowing flax; irrigation once 7-10 days before sowing, use directly The planter is used for sowing, and the flaxseed is treated with carbendazim of 0.2% of the seed weight. The seed dressing time is arranged 2 weeks before the sowing date; if possible, sow as early as possible to extend the growth time of flax at low temperature, and A longer physiological growth period is conducive to enhancing the ability of flax to resist lodging. After entering March, the temperature will continue to be higher than 4 degrees Celsius before ...

The invention relates to the technical field of crop cultivation, in particular to a cultivation method for improving lodging-resistance capability of flax. The cultivation method comprises the following steps: irrigating a flax field 6 to 12 days before spring sowing, and sowing the flax in mode of deep groove and shallow covering, wherein the sowing density is 1,200 to 2,600 seeds / m<2>; applyingbase fertilizer after the flax is sown; hilling the roots of the flax in an elatocladus model period; applying potassium sulphate fertilizer in an early stage of rapid growth, and irrigating after the fertilizer is applied; and spraying a flower suppression agent in a flowering period. According to the cultivation method, the lignin content and the stem diameter of flax plants are comprehensivelyimproved and the gravity centres of the plants are reduced by regulating a sowing period and a sowing mode and regulating and controlling auxin, so that the lodging-resistance capability of flax is greatly improved.
Description
Technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a cultivation method for improving the lodging resistance of flax. Background technique [0002] Flax fiber is of high quality and is known as the queen of fiber. It is an important oil-fiber dual-use economic crop in the world. Flaxseed is rich in nutrients, rich in linolenic acid, lignans, flax gum and other beneficial substances to the human body. Because of its high content of linolenic acid, cold-pressed linseed oil has a very good health effect on the human body and is very popular in the market. Lignan has been proved to have good curative effect on breast cancer and bowel cancer. Flax gum is a good dietary fiber. It has the effects of weight loss, beauty, nutrition and health care. It has a certain effect in reducing the incidence of diabetes and coronary heart disease, preventing colon cancer and rectal cancer, and reducing the incidence of obesity. Used to make n...
